Description

Ethylenediaminetetraacetic Acid, Di-Sodium-Magnesium Salt is a stable, water-soluble chelating agent derived from EDTA. This compound is valued for its ability to effectively sequester di- and trivalent metal ions, preventing unwanted precipitation and catalytic activity in complex formulations. It is essential for manufacturers in the personal care, pharmaceutical, and industrial cleaning sectors who require a reliable, multi-valent chelant with good compatibility.

Application

• Personal Care & Cosmetics: Acts as a chelating agent in shampoos, creams, and lotions to stabilize formulations by inactivating trace metal ions that can cause rancidity and discoloration.
• Pharmaceuticals: Used as a stabilizing agent in liquid preparations and topical products to enhance shelf-life by chelating pro-oxidant metals.
• Industrial Cleaners & Detergents: Improves the efficiency of cleaning formulations by softening water and preventing soap scum and scale formation.
• Agriculture: Employed in certain micronutrient fertilizer formulations and agrochemicals to improve the bioavailability and stability of metal ions.
• Textile Processing: Serves as a chelant in dyeing and bleaching baths to control water hardness and ensure consistent color results.
• Pulp & Paper Industry: Helps in peroxide bleaching processes by deactivating metal ions that catalyze the decomposition of bleaching agents.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking.
